摘要

本文研究了一种新兴的集成传感、通信和供电（ISACP）系统的波束成形设计，其中多功能发射机处理传感、数据通信和功率传输任务。我们的目标是通过共同优化发射波束形成矢量、雷达协方差和接收功率分割比，使受通信、能量收集和发射功率限制的传感匹配误差最小化。虽然原问题是非凸的，但我们利用半确定松弛方法来获得全局最优解。仿真结果验证了所提方案的有效性。

Optimal Beamforming for Multi-Functional Integrated Sensing, Communication, and Powering Systems

This letter investigates the beamforming design for an emerging integrated sensing, communication, and powering (ISACP) system, where a multi-functional transmitter handles sensing, data communication, and power transfer tasks. Our goal is to minimize the sensing matching error, subject to communication, energy harvesting, and transmit power constraints, by jointly optimizing transmit beamforming vectors, radar covariance, and receive power splitting ratios. Although the original problem is non-convex, we utilize the semi-definite relaxation approach to achieve a globally optimal solution. Simulation results demonstrate the effectiveness of our proposed schemes.
